VertexArray

Represent an OpenGL vertex array. The vertex data must be set with {@link #setData(org.spout.renderer.api.data.VertexData)} before it can be created.

abstract

class VertexArray : Creatable , GLVersioned {

void destroy();

void setData(VertexData vertexData);

void setDrawingMode(DrawingMode mode);

void setPolygonMode(PolygonMode mode);

void setIndicesOffset(uint offset);

void setIndicesCount(uint count);

uint getID();

Functions

destroy void destroy(): Undocumented in source. Be warned that the author may not have intended to support it.
draw void draw(): Draws the primitives defined by the vertex data.
getID uint getID(): Gets the ID for this vertex array as assigned by OpenGL.
setData void setData(VertexData vertexData): Sets the vertex data source to use. The indices offset is kept but maybe reduced if it doesn't fit inside the new data. The count is set to the size from the offset to the end of the data.
setDrawingMode void setDrawingMode(DrawingMode mode): Sets the vertex array's drawing mode.
setIndicesCount void setIndicesCount(uint count): Sets the number of indices to render during each draw call, starting at the offset set by {@link #setIndicesOffset(int)}. Setting this to a value smaller than zero results in rendering of the whole list. If the value is larger than the list (starting at the offset), it will be maxed to that value.
setIndicesOffset void setIndicesOffset(uint offset): Sets the starting offset in the indices buffer. Defaults to 0.
setPolygonMode void setPolygonMode(PolygonMode mode): Sets the vertex array's polygon mode. This describes how to rasterize each primitive. The default is {@link org.spout.renderer.api.gl.VertexArray.PolygonMode#FILL}. This can be used to draw only the wireframes of the polygons.

Variables

id uint id;: Undocumented in source.

Inherited Members

From Creatable

create void create(): Creates the resources. It can now be used.
destroy void destroy(): Releases the resource. It can not longer be used.
isCreated bool isCreated(): Returns true if the resource was created and is ready for use, false if otherwise.
checkCreated void checkCreated(): Throws an exception if the resource hasn't been created yet.
checkNotCreated void checkNotCreated(): Throws an exception if the resource has been created already.

From GLVersioned

getGLVersion GLVersion getGLVersion(): Returns the lowest OpenGL version required by this object's implementation.
